I expect this is the issue. We haven't updated the VM link on the OpenFlow tutorial page yet, so it still points to an older VM which may have an older version of cbench.
If you're running that older VM you can update your oflops branch in place and rebuild, or you can delete it and reinstall it using mininet/util/install.sh -b. You are also welcome to download and try out a newer Mininet/tutorial VM from https://github.com/mininet/mininet/downloads or http://yuba.stanford.edu/foswiki/bin/view/OpenFlow/MininetGettingStarted If you run into errors with it, drop us a line on mininet-discuss. -Bob On Jun 1, 2012, at 12:47 PM, Rob Sherwood wrote: > On Wed, May 30, 2012 at 1:24 PM, Salman Malik <[email protected]> wrote: >> Thanks for the quick reply Rob. >> In my configuration I am using two VMs connected in a host-only network mode >> and I can ping fine between the two VMs. And while using cbench I see the >> right src/dst IPs in the packets when the switches send 'Hello' messages to >> the controller but rest of the messages have 192.x.x.x type of addresses. >> Furthermore, even when using it with the local host I see some of the >> packets with these 192.x.x.x addresses.
